Invisibility cloak now 5 minutes from production

Ah hah, now all your Harry Potter fantasies can come true. No, not the ones about Hermoine and that flying car but all the ones about invisibility cloaks. Using magic material that bends light in the opposite direction it should now be a relatively easy step to make an invisibility cloak or pretty much an invisible anything. Wow, think of the possibilities, an invisible Barbara Striesand, no one would ever have to look at that nose again. Or an invisible English cricket team, oh wait we already had that, that's why they lost the ashes 5-0, hahahahahahah.
